220-1102 Question 258
Single answertracerouteA user reports that they can access internal company websites but cannot reach a cloud-based ticketing site. The technician verifies that the PC has a valid IP address, can browse other internet sites, and can ping the default gateway successfully. To determine where along the network path the connection is failing, which command should the technician run next on the Windows PC?
- A
tracert tickets.examplecloud.com
- B
ipconfig /renew tickets.examplecloud.com
- C
net use \tickets.examplecloud.com\share
- D
nslookup /flushdns tickets.examplecloud.com
Show answer and explanation
Correct answer: A
Explanation
The best answer is "tracert tickets.examplecloud.com" because traceroute functionality is specifically designed to identify the path packets take to a remote destination and reveal at which hop communication stops or degrades. In Windows, the command is tracert; on many Linux and macOS systems, the equivalent command is traceroute. This aligns with standard troubleshooting methodology: first verify local connectivity and IP configuration, then test the route to the remote resource when only a specific destination is failing. Microsoft documentation for Windows networking tools describes tracert as a utility that tracks the path to a network host by sending packets with incrementing TTL values and reporting the routers that respond at each step. This makes it appropriate for isolating whether the issue is local, at the ISP, or farther upstream.
- A. Correct.
Correct. On Windows, the tracert command is used to trace the route that packets take to a remote host and identify where delays or failures occur between the source and destination. In this scenario, the technician already knows the PC has basic connectivity, so the next practical step is to map the path to the cloud service and see whether the issue occurs at the local router, ISP, or a remote hop.
- B. Incorrect.
Incorrect. ipconfig /renew is used to request a new IP lease from a DHCP server for a network adapter. It does not test the hop-by-hop path to a remote website, and it does not take a hostname as an argument in this way. Someone might choose this if they suspect an addressing problem, but the scenario already confirms that the PC has a valid IP address and general internet access.
- C. Incorrect.
Incorrect. net use is used to connect to shared network resources such as SMB file shares. It is not a troubleshooting tool for determining the route to a web-based cloud application over the internet. This distractor reflects a common confusion between accessing a network resource and diagnosing path-related connectivity issues.
- D. Incorrect.
Incorrect. nslookup is used to query DNS records, and /flushdns is not a valid nslookup switch on Windows. Flushing the DNS cache is done with ipconfig /flushdns. Even if DNS were being checked, the scenario specifically asks for the next command to determine where along the network path the failure occurs, which is the purpose of tracert.
